"Strangely enough, they are very similar to what we hear at Jupiter and Earth," says Kurth.

The reason for the similarity is that all three planets, along with Neptune, Uranus, Mercury and even Jupiter's moon Ganymede, generate their own magnetic fields that interact with charged particles steaming out from the sun.

When those particles are channelled to the magnetic poles of planets, they can create strange lights and other electromagnetic radiation, including radio waves.

"What's happening is all of the electrons bundle up together and spontaneously emit the electrical field" that is detectable as radio waves, says team member, Dr Don Gurnett, a pioneer of planetary radio emissions, also of the University of Iowa.
